Uploading Attachments via Unirest

I am trying to use unirest to upload attachments in memory to avoid having to download and reupload the files. I have successfully made this happen, however, the content-type for the file is defaulting to application/octect-stream. I tried setting content-type in the header, but it doesn’t seem to like that. Does anyone have any insight on how to set the content-type for attachments using unirest?

Here is the code that is working with the wrong content-type:

  function update_ticket(args){
	var domain = kiskadomain;
	var api_key = kiskaApiEncode;

	var url = `${domain}/api/v2/tickets/${args.id}`;		


	unirest.put(url)
		.headers({  
            Authorization : "Basic " + api_key
        })
		.attach('attachments[]', args.url)
		.end(function (response) {
			console.log(response.body);
			if (response.status === 200) {	
				console.log({"body": response.body.ticket.attachments, "status": response.status});
			}else{
				console.log({"body": response.body, "status": response.status});
			}
		});
}

Here is the code that I have come up with thus far:

  function update_ticket(args){
	var domain = kiskadomain;
	var api_key = kiskaApiEncode;

	var url = `${domain}/api/v2/tickets/${args.id}`;		


	unirest.put(url)
		.headers({  
            Authorization : "Basic " + api_key
        })
		.attach('attachments', args.arr)
		.end(function (response) {
			console.log(response.body);
			if (response.status === 200) {	
				console.log({"body": response.body.ticket.attachments, "status": response.status});
			}else{
				console.log({"body": response.body, "status": response.status});
			}
		});
}

//args looks like
args = {
                    size: ticattach.attachments[0].size,
                    id: 183,
                     arr : [
                        ticattach.attachments[0].content_type,
                        ticattach.attachments[0].attachment_url
                    ]
                }

This is throwing an error of “Invalid value “undefined” for header “Content-Length””
